目的掌握艾滋病疫情状况,评估扩大检测工作效果,为艾滋病防治政策的制定提供依据。方法收集邵阳市近年来人口学、艾滋病病例报告、高危人群规模及感染率等资料建立艾滋病疫情估计数据库,应用工作簿法(workbook模型)对邵阳市2017年艾滋病疫情进行估计,并将结果和2016年病例报告数进行比较分析。结果邵阳市高危人群规模总数349 200~476 400人,其中注射吸毒7 200~14 400人,男男同性恋12 000~22 000人,暗娼30 000~40 000人。估计2017年底现存活感染HIV总人数为4 880人,全人群总感染率为0.061%。HIV感染者和病人发现比例57.7%,按性别统计男性病例发现比例73.7%,女性发现比例51.0%;按传播途径统计异性传播发现比例63.5%,同性传播病人发现比例33.8%,注射吸毒病人发现比例61.2%。结论邵阳市仍处于艾滋病低流行态势,但是高危人群规模较大,还有将近三分之一的病人没有被发现,在下一步工作中,需重点加强男男同性恋高危人群干预和女性暗娼及配偶的检测工作,扩大艾滋病抗体检测覆盖面,尽量多的发现感染者。
Objective To grasp the status of AIDS epidemic, evaluate the effect of expanding the detection work and provide the basis for the formulation of AIDS prevention and control policy. Methods To collect AIDS epidemic estimation database from demographic data, AIDS case reports, high-risk population size and infection rate in Shaoyang city in recent years, and estimate the 2017 epidemic situation in Shaoyang City using the workbook method (Workbook model) and compare the results with 2016 The number of cases reported were compared. Results The total number of high-risk groups in Shaoyang was 349 200-476 400, among which 7 200-1440 were injecting drug abusers, 12 000-22 000 men and 100% gay male and 30 000-40 000 female sex workers. It is estimated that the total number of HIV-infected persons currently living at the end of 2017 will be 4,880 and the total infection rate of the entire population will be 0.061%. 57.7% of HIV-infected persons and patients were found, accounting for 73.7% of male cases and 51.0% of female cases by sex; 63.5% of heterosexual transmission by transmission, 33.8% of same-sex transmission cases, 61.2%. Conclusion Shaoyang City is still in a low HIV prevalence situation, but the high-risk population is larger and nearly one-third of patients are still undetected. In the next step, it is necessary to focus on strengthening the intervention among men who have sex with men and female sex workers and their spouses Testing, expanding coverage of HIV antibody testing, as many as possible to find those infected.
